SAW-OILER.

Specification of Letters Patent. P te ted Mar. 24 1914i.

Application filed March 12, 1913. Serial N0. 753,865.

Y fwhich the following is a specification, reference being had to the accompanying drawlngs.

This invention relates to new and useful improvements in saw oilers and more particularly to an oiler which is adapted for application to hand saws, cross cut and various other types of handsaws, 'the object of the invention being to provide an oiler which is to m be applied to the handle of the saw so that the same may be readily actuated to oil the saw blade while in operation.

Another object of the invention is to provide a sawoilerof the above type which will possess advantages in points of efiiciency and durability, is inexpensive of manufacture and at the same time is simple in construction and operation.

With the above and other objects in view the invention consists in the novel features of construction and the combination and arrangement of parts hereinafter more fully described pointed out in the claims and shown in the accompanying drawings in which Figure 1 is a side elevation showing the application of my improved oiling device toa saw handle; Fig. 2 is a longitudinal sectional view; and Fig. 3 is a transverse sectional view.

Referring more particularly to the drawings, 1 indicates the handle of a well known form of hand saw upon which is mounted my improved oiler.

The oiler as shown in the accompanying drawings comprises a tubular body2,which is arranged within a suitable socket formed in the handle 1 and is provided adjacent its upper end with an air opening 3. Mounted for reciprocatory movement within the body 2, is a piston rod 4 having a reduced threaded end 5 forming a suitable shoulder 6. Mounted upon the reduced end 5 is a piston head 7 which is of sulficient diameter to fit snugly within the body 2, said head abutting against the shoulder 6 to limit the upward movement of the same. A nut 8 is threaded upon the inner end of the rod 4 to securely hold the head 7 upon the end of the rod.

Threaded upon the upper end of the body 2 and adaptedto close the open end of the same is a cap 9 having a centrally arranged opemn 10 in which the upper end of the rod 4 1s slldably mounted. Formed upon the upper end of the rod 4 is an enlarged headll which is adapted to be engaged by the thumb or finger to reciprocate the rod 4.

any suitable manner adjacent one end there of 1s a tube 12 which communicates at its inner end with the interior of thebody 2, the-outer end of said tube extending out upon the saw blade so that the oil in the body may be readily transferred to the saw blade. This tube 12 is arcuately curved to conform to the lower curved end of the handle 1 andadapted to engage with the same to securely hold the body 2 against movement. It will also be apparent from the showing in the accompanying drawings that the outer end of the tube 12 is divided Formed upon or secured to the body in I by means of the slit 12 so that each half of the tube is disposed upon opposite sides of the saw blade to convey the oil to both sides of the blade.

Arranged within the inner end of the body 2 and disposed between the inner closed end of the body and the head 7 is a coil spring 13 which is adapted to normally hold the head 7 over the inner end of the tube 12 to prevent the oil from flowing therein until it is desired to use the same.

In using my improved oiler, it will be obvious that when the saw blade starts to bind during the sawing operation, the operator will press upon the head 11 to open communicationbetween the tube 12 and the body 2, allowing the oil contained within the body, to flow out upon the saw blade. After pressure has been released from the head 11 the coil'spring 13, which has been placed under tension of the downward movement of the rod 4, will return the piston head 7 to its normal position and close the opening to the tube 12. J

It will be apparent from the foregoing, that I have provided a simple and durable oiler which is particularly adapted to various types of hand saws and whereby the saw blade may be quickly and readily oiled dur ing the sawing operation. It will also be apparent that I have provided an oiler which is extremely simple in construction and operation and can be manufactured at a comparatively low cost.

While I have shown and described the preferred form of my invent-ion, it will be obvious that various changes in the details of construction and in the proportions may be resorted to for successfully carrying my invention into practice without sacrificing any of the novel features or departing from the scope of the appended claims.

Having thus described the invention, what is claimed is:

l. The combination with a tool handle provided with an obliquely disposed opening, of a cylindrical container removably mounted in said opening, a threaded closure cap for one end of said container adapted for engagement with one edge of the handle to prevent longitudinal movement of the container in one direction, a curved tube extending laterally from the container adjacent its other end and closely engaged with the opposite edge of the handle to prevent longitudinal movement of the container in said handle in the other direction, the extremity of said tube being longitudinally split to provide a divided bore and to receive the tool blade, and manually operable means arranged within the container to open comtioned within said recess, a lubricant conveymg tube extending at an angle to the contamer and from the latter to the blade, said tube communicating at one end with the container and being adapted to feed a lubricant from its other end upon the blade, an apertured cap closing the upper end of the container, a spring pressed slide valve normally closing the inner end of the conveying tube, and a valve stem carried by the valve and extending through the apertured cap whereby it may be conveniently operated by thumb pressure to open the conveyingi'tube.

In testimony whereof I hereunto a signature in the presence of two witnesses.
